Small Extracellular Vesicle-Mediated Itgb6 Sirna Delivery Downregulates The Αvβ6 Integrin And Inhibits Adhesion And Migration Of Recipient Prostate Cancer Cells, Shiv Ram Krishn, Vaughn Garcia, Nicole M Naranjo, Fabio Quaglia, Christopher D Shields, Maisha A Harris, Andrew V Kossenkov, Qin Liu, Eva Corey, Dario C Altieri, Lucia R Languino

Department of Cancer Biology Faculty Papers

The αVβ6 integrin, an epithelial-specific cell surface receptor absent in normal prostate and expressed during prostate cancer (PrCa) progression, is a therapeutic target in many cancers. Here, we report that transcript levels of ITGB6 (encoding the β6 integrin subunit) are significantly increased in metastatic castrate-resistant androgen receptor-negative prostate tumors compared to androgen receptor-positive prostate tumors. In addition, the αVβ6 integrin protein levels are significantly elevated in androgen receptor-negative PrCa patient derived xenografts (PDXs) compared to androgen receptor-positive PDXs. In vitro, the androgen receptor-negative PrCa cells express high levels of the αVβ6 integrin compared to androgen receptor-positive PrCa cells. Additionally, expression ...

Purpose: Local treatment for bone metastases is becoming increasingly complex. National guidelines traditionally focus only on radiation therapy (RT), leaving a gap in clinical decision support resources available to clinicians. The objective of this study was to reach expert consensus regarding multidisciplinary management of non-spine bone metastases, which would facilitate standardizing treatment within an academic-community partnership.

Methods and Materials: A multidisciplinary panel of physicians treating metastatic disease across the Memorial Sloan Kettering (MSK) Cancer Alliance, including community-based partner sites, was convened. Clinical questions rated of high importance in the management of non-spine bone metastases were identified via survey. A literature ...

Tumor Vasculature Changes Before Or During Treatment To Predict Response To Systemic Therapy, Avinash Ramkissoon, Faria Ali, Thomas Vander Woude, Stephen Brown, James Ewing, Lisa Rogers

Medical Student Research Symposium

A diagnosis of non-small cell lung cancer (NSCLC) carries a grim prognosis, with 5-year survival rates of 25%. 25-30% of NSCLC patients have brain metastases at initial presentation, which carries an even worse prognosis. New systemic therapies such as targeted-therapies and immuno-therapies have potential to provide better outcomes, but are not without challenges. First, efficacy is limited to a subset of patients. Second, the blood-brain barrier limits penetration, which varies among patients. Third, toxicities can be considerable. Current practice involves waiting 3-6 months to follow-up and assess tumor response; however, by then, it is later than ideal to try other ...

Enriching The Perioperative Enhanced Recovery After Surgery (Eras) Program For Patients Undergoing Whipple Procedure For Pancreatic Cancer, Natalie E. Fisher

Doctor of Nursing Practice Final Manuscripts

Pancreatic cancer remains one of the most complex and lethal diseases worldwide with surgical resection as a major treatment choice. Although surgery may be one of the only options for advanced pancreatic cancer, it is not without a lengthy hospital stay, a long list of possible postoperative complications, and an increased risk for readmission after discharge. Enhanced recovery after surgery (ERAS) programs have been implemented for years in other surgical services for cancer care. These programs have now been extended and researched to include patients undergoing surgery for pancreatic cancer. These programs are designed to assist patients and their families ...

Moving Through Loss: The Experience Of Ambiguous Loss With Hospitalized Children, The Development Of A Method, Peyton Edington

Expressive Therapies Capstone Theses

The current method examined the effects of ambiguous loss with medical transplant patients in a pediatric hospital by utilizing a dance/movement therapy intervention. The development of this method was based on ambiguous loss theory with a dance/movement therapy approach. The explored literature identified central themes of ambiguous loss, such as resilience. These themes were connected to the practice of dance/movement therapy, such as embodiment. With this connection, the intervention was developed and implemented with participants. The central themes that emerged from the intervention were change, loss, meaning-making, and hope. One child and two adolescents were participants in ...

Igm Multiple Myeloma: A Rare Clinical Entity And Diagnostic Dilemma, Keerthy Joseph, Alison Greidinger, Marjan Koch, Eric Behling, Tulin Budak-Alpdogan

Cooper Rowan Medical Journal

IgM multiple myeloma is a rare disease that shares many common features with Waldenström macroglobulinemia and lymphoplasmacytic lymphoma. It has been described in the literature as having unique diagnostic findings that separate it from the more common IgG and IgA myelomas. It is important for physicians to be able to differentiate between IgM multiple myeloma, Waldenström macroglobulinemia and lymphoplasmacytic lymphoma as their treatments vastly differ. This case report describes the clinical presentation of a patient with IgM lambda multiple myeloma and highlights the pathologic and clinical findings that are specific to this rare entity. We aim to provide further evidence ...

Variation In Thiopurine Metabolism In Hispanic Children, Kayeleigh Higgerson Do

Research Days

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Overall survival rate is > 90% in the United States. However, ethnic and racial disparities remain. Hispanic patients have an inferior overall survival compared to non-Hispanics. The reasons for these differences remain unclear. Mercaptopurine (6MP) is a crucial drug in ALL treatment. Variations in the TMPT and NUDT15 genes lead to altered 6MP metabolism and accumulation of toxic metabolites (6TGN or 6MMPN). Each metabolite is associated with specific dose-limiting toxicities. The accumulation of 6TGN causes myelosuppression, and increased 6MMPN causes GI toxicity. While variants in these genes have been identified ...

Wilms Tumor Presenting With Spontaneous Necrosis And Clostridium Perfringens Co-Infection, Ronald Palmen, Abbey Elsbernd, Kristin Palmen

Research Days

Background: Wilm’s Tumor (WT) is the most common renal malignancy of childhood. The initial presentation of WT may mimic infection or other malignancies with nonspecific symptoms including fever, abdominal/flank pain, or hematuria. This poses a diagnostic challenge for providers, particularly when both infection and malignancy are observed. We describe a case of WT with spontaneous necrosis initially obscured by overlying Clostridium perfringens infection, making diagnosis of the cancer difficult.

Case Description: A previously healthy 5-year-old girl presented to the emergency department with a two-day history of left flank pain and fevers. In the emergency department, she was tachycardic ...

Combined Treatment With Niclosamide And Camptothecin Enhances Anticancer Effect In U87 Mg Human Glioblastoma Cells, Laura Valdez, Benxu Cheng, Daniela Gonzalez, Reanna Rodriguez, Paola Campano, Andrew Tsin, Xiaoqian Fang

School of Medicine Publications and Presentations

Glioblastoma multiforme (GBM) is one of the deadliest cancers of the brain. Its ability to infiltrate healthy brain tissues renders it difficult to remove surgically. Furthermore, it exhibits high rates of radio- and chemoresistance, making the survival rates of patients with GBM poor. Therefore, novel effective therapies for GBM remain urgently in demand. Niclosamide is an anti-helminthic drug and recently it has been receiving attention due to its reported anticancer effects in cancer models, including GBM. Furthermore, camptothecin (CPT) is a naturally-occurring alkaloid and has been previously reported to be a potential chemotherapeutic agent by targeting the nuclear topoisomerase I ...

Case Report: Glioblastoma Tumor Presenting With Mild Changes In Memory, Samuel Thalathoti, Nicholas Palladino, James Espinosa, Alan Lucerna

Stratford Campus Research Day

We report a case of a 66-year-old female who presented to the ED with generalized headache and mild confusion, who was diagnosed with high-grade glial neoplasm. The differential diagnosis of headache is vast, but without red flags or symptoms is generally from a benign cause and easily treatable. However, even in the context of a normal neurologic physical exam, symptoms such as confusion, forgetfulness, and behavioral changes should merit imaging in the workup. Glioblastoma is the most common brain tumor, accounting for 47.7% of all cases, with an incidence of 3.21 per 100,000 population. Median age of ...

Primary Venous Thromboprophylaxis In Pediatric Oncology Patients, Kyra Mccarty

Research Days

Background: The Virchow’s Triad principles of venous stasis, endothelial damage, and hypercoagulability are all features of malignancy and contribute to the increased risk venous thromboembolism (VTE) seen in oncology patients. Additionally, certain chemotherapy treatments, presence of a central venous catheter and immobility are also intrinsically associated with malignancy diagnoses and exacerbate this risk. However, much debate exists over the use of thromboprophylaxis in the pediatric population, primarily due to lack of evidence regarding safety and efficacy, primarily the risk of major bleeding. Multiple retrospective studies have attempted to identify the primary risk factors for VTE in this pediatric oncology ...

A Novel Approach To Triosephosphate Isomerase Deficiency, Kyra Mccarty

Research Days

Background: Triosephosphate isomerase deficiency (TPID) is a glycolytic pathway enzymopathy causing hemolytic anemia and neurologic dysfunction. TPID is caused by mutations in the TPI1 gene. These patients experience severe hemolytic anemia in infancy followed by progressive neurodegeneration. Diagnosis of TPID is made by measuring decreased TPI enzyme activity elevated dihydroxyacetone phosphate (DHAP) levels in the blood. The diagnosis is confirmed by molecular genetic testing. Neurological involvement typically manifests between 6 and 24 months of age, causing progressive motor dysfunction. Chronic axonal neuropathy is often present on nerve biopsy, and peripheral neuropathy is evident on electrophysiologic studies. Splenectomy and blood transfusions ...

Kimmel Cancer Center Faculty Papers

Background: Cancer centers are expected to engage communities and reduce the burden of cancer in their catchment areas. However, the extent to which cancer centers adequately reach the entire US population is unknown. Methods: We surveyed all members of the Association of American Cancer Institutes (N ¼ 102 cancer centers) to document and map each cancer center’s primary catchment area. Catchment area descriptions were aggregated to the county level. Catchment area coverage scores were calculated for each county and choropleths generated representing coverage across the US. Similar analyses were used to overlay US population density, cancer incidence, and cancer-related ...

The Future Of Targeted Kinase Inhibitors In Melanoma, Signe Caksa, Usman Baqai, A E Aplin

Department of Cancer Biology Faculty Papers

Melanoma is a cancer of the pigment-producing cells of the body and its incidence is rising. Targeted inhibitors that act against kinases in the MAPK pathway are approved for BRAF-mutant metastatic cutaneous melanoma and increase patients' survival. Response to these therapies is limited by drug resistance and is less durable than with immune checkpoint inhibition. Conversely, rare melanoma subtypes have few therapeutic options for advanced disease and MAPK pathway targeting agents show minimal anti-tumor effects. Nevertheless, there is a future for targeted kinase inhibitors in melanoma: in new applications such as adjuvant or neoadjuvant therapy and in novel combinations with ...

Integration Of Biomedical Imaging And Translational Approaches For Management Of Head And Neck Cancer, Abdallah Mohamed, Abdallah Mohamed

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

The aim of the clinical component of this work was to determine whether the currently available clinical imaging tools can be integrated with radiotherapy (RT) platforms for monitoring and adaptation of radiation dose, prediction of tumor response and disease outcomes, and characterization of patterns of failure and normal tissue toxicity in head and neck cancer (HNC) patients with potentially curable tumors. In Aim 1, we showed that the currently available clinical imaging modalities can be successfully used to adapt RT dose based-on dynamic tumor response, predict oncologic disease outcomes, characterize RT-induced toxicity, and identify the patterns of disease failure. We ...
